Research has been done for the calibration of a thermal infrared imaging system for the measurement of transmission line conductor sample emissivities. The spectral response of the imaging system was from 8 to 12 micrometers. A laboratory set-up was designed and built for this analysis. The laboratory equipment consisted of a FLIR 1000a thermal infrared imaging system, a stainless steel black-body source with dual emissivity front surface coatings, an Elexor Industries PL1000 data acquisition and control system, and an IBM personal computer AT with imaging board and imaging software. The emissivities of the conductor samples were obtained through the analysis of thermal infrared images of each conductor with a blackbody cavity and low emissivity source simultaneously imaged as references. This analysis gave statistical mean grey levels for each conductor sample and references. From these mean grey levels the emissivity of the conductor samples were computed. Nine transmission line conductor sample emissivities where measured to an average accuracy of 17.5%. The emissivities ranged from .451 to .959.
